Drought and low organic-matter-content of soil and intensive-movement of agricultural-machines result in soil-compaction and inducing some problems in soil-aeration, infiltration, and the availability of nutrient-elements which consequently result in yield-reduction and even plant-death. In order to studying the effect of soil-compaction (bulk-densities of 1.3, 1.5, and 1.7 g cm-3) and organic-matter(manure and sewage-sludge of 2 and 4 %W, respectively) application on nitrogen-mineralization, columns of three calcareous-soils of Daneshkadeh(Clay) and Kooyeh-Asatid(Silty-clay-loam) series of Bajgah and Chitgar(Clay-loam)-series of Sarvestan from Fars-province with the mentioned bulk-densities were prepared after mixing the soils with the organic-matters. The prepared-soil-columns were maintained at 25-30 ºC temperature and field-capacity-conditions(water-contents of 16-20%W depend on the soil-type). Total-N, nitrate and ammonium were measured in soil-columns after 50-days. At the end of experiment the total-N and ammonium-contents of Daneshkadeh-soil-series were significantly higher than the others, while the nitrate-content of studied-soils were not significantly different(P
